TY PE-WRITING MACHINE.

SPECIFICATION forming part of Letters Fatent No. 681,750, dated September 3, 1901. Application filed November 16, 1896. Serial No. 612,240. (No model.)

To all whom it may concern:

Be it known that we, BURNHAM O. STIcKNnY and CARL GABnInLsoN, citizens of the United States, and residents of Elizabeth, in the county of Union and State of New Jersey, have invented certain new and useful Improvements in Type-Vriting Machines, of which the following is a specification.

Our invention relates to brushes for cleaning the types in type-writing machines; and its object is to improve the construction and simplify the operation thereof.

The invention consists in the combination, with a series of types, of one or more rotary brushes arranged without the type-field and adapted when rotated to be moved by the action of centrifugal force into contact with the types; and it further consists in the various features of construction and combinations of devices hereinafter more fully described, and particularly pointed out in the appended claims.

In the accompanying drawings, Figure 1 is a front elevation, partly in section, of our improvement as applied to a type-writing machine. Fig. 2 is a plan showing the brushes in operative position. Fig. 3 gives views of various details, and Fig. eillustrates another method of lifting the brushes by means of centrifugal force.

In the several views similar numerals of reference designate similar parts.

1 represents the side wall of the base of a type -writing or similar type striking machine; 2, the top plate or type-bar ring; 3, the usual posts extending from the base to support the top plate, and 4 the rear Wall of Swinging type-bars 5 depend from the top plate and are provided with an annnlar type-basket 6.

Any number of type-brushes (designated by the numerals 7 8 9 10) may be employed. The brushes are connected to a centrally-arranged vertical rotary shaft 11. The shaft is provided with a small bevel gear-wheel l2, meshing with which is a larger bevel gearwheel 13, arranged upon the inner end of a horizontal shaft 14, which protrudes through the side wall of the base and is provided with a crank 15, whereby it may conveniently be rotated. The shafts and appurtenances are supported in a bracket 16, secured to the framework of the machine. The outer end of shaft 14, however, is journaled in the wall of the base. At its inner end the bracket is forked to provide a long bearing for the Vertical shaft 11. The brushes, guards, supports, &c., are secured to the portion of the shaft projecting above the bracket; The small gear-wheel is secured to the shaft at a point below the upper bearing. Normally the brushes lie in the position shown in full lines at 8 and in dotted lines at 10. In this position they lie outside of the type-field 2'. 6., outside of the space occupied by the types in swinging to make their impressions, as indicated by the dotted curves 5 To clean the types, the crank 15 is turned in either direction, and rotary motion is thereby communicated through shaft let and gear 13 to gear 12 and shaft 11. The latter rotates at an accelerated speed, owing to the diderence in size of the gear-wheels. The brushes rotate with shaft 11, and by the action of centrifugal force they swing or fly outward and upward about the pivots 17 until they reach the position shown in full lines at 10, where they fly around at a right angle to the shaft 11 and in contact with the types. This flying position is maintained by the brushes so long as crank 15 is turned. Upon diminishing the speed or ceasing to turn the crank the brushes will fall by gravity to normal position. To facilitate the prompt return of the brushes, the brush-handles are broken and the two parts pivoted to each other at 18, Fig. 3, so that at the cessation of the rotary motion the brush collapses, the link 19 swings by gravity down about the pivot 17, the inner end of the brush falling with it, until the position of the parts shown by dotted lines at 8 is reached or until the bristles are freed from the types, whereupon the outer end of the brush also falls. Without the joint 18 the bristles by catching upon the types would be likely to hinder the prompt collapse or return of the brushes to normal position. The link 19 is provided with ashort arm 20, which contacts with the shoulder of the brush at 21 and limits the motion thereof about the pivot 18.

In the above-described mechanism for carrying out our invention the link 19, the handle, and the body of the brush taken together constitute a swinging weight, which upon rotation is acted upon by centrifugal force, so thatit-swings upwardly and outwardly,whereby the type-cleaning end of the brush is carried into contact with the types.

The brushes are pivotally connected to the shaft 11 in the following manner: A collar 22, Fig. 3, fixed upon the shaft, is provided with an upper flange 23 and a lower flange 24. Flange 23 is slotted, as at 25, to receive the links 19, and it is also provided on its upper surface with a circular groove 26. A cap 27 is provided with a similar groove in its lower surface, also with slots to match the slots 25. In assembling a wire ring 28 is passed through the pivot-holes 17 of the links 19, which are then arranged in the slots, the ring fitting in the circular grooves. The cap 27 is then soldered, screwed, or riveted to the flange 23, securing the links in place and permitting them to swing about the pivots 17, the ring 28 serving for all the pivots. The lower flange 24 supports the brushes when in normal position, the arms 20 resting thereon. The shaft 11 is also provided with a topguardplate 29, which prevents accidental upward displacement of the brushes. This guardplate and the cap 27 are omitted from Fig. 2, so as to make clear the manner of stringing the links 19 upon the wire ring 28 and their arrangement in the slots 25.

As illustrated at Fig. 1, the faces of the types may be arranged at different heights and the brushes are sufficiently large to clean them all. concentric curve, as shown by dotted lines at Fig. 2. If desired, the bristles may be bound together, as at 30, to make the brush stiffer and more effective.

At Fig. 4 the vertical motion of the brushes them to a pair of pendulums similar to those used in governors for steam-engines. Upon turning the crank the pendulums are swung outwardly by the action of centrifugal force, and by means of suitable connections the brushes are thereby elevated into the typefield. The shaft 11 is rotated by means of gears 12 13 and crank-shaft 14, as in the other views. A collar 31 is secured to the shaft 11, to which are pivotally secured two hanging weights 32. Arranged near the top of the shaft and adapted to slide thereon is a cross-bar 33, provided at its ends with typecleaning brushes 34. A circular brush may be employed, if preferred, in place of a cross bar with two brushes. Links 35 are pivoted at their upper ends to two arms that depend from the cross-bar 33 and at their lower ends to the free ends of arms 36, with which the pendulums are provided. Upon the crank The type-bars are arranged in a being turned rotary motion will be imparted to shaft 11, collar 31, and weights 32, which will swing outwardly upon their pivots, as indicated by the curved arrows,and by means of arms 36 will lift the links 35 and the crossbar 33 with its brushes 34. A stop-pin 37 at the top of the shaft limits the upward motion of the parts. The brushes will sweep across the faces of the types as long as the crank is turned, and upon cessation of the crank motion the parts will return by gravity to normal position. To assist such return, the arms of the cross-bar may, if desired, be made collapsible in the same manner as shown in the other figures with reference to the brushhandles.

If desired, other than the described means may be employed to rotate the brushes, or other type-cleanin g devices than brushes may be employed, or different means for moving the brushes from normal to active position, and vice versa, or for performing various other offices of the invention. The means we have described for performing the various functions are those preferred by us; but, so far as the broad features of our invention are concerned, it is not our intention to limit ourselves to such means.

so far as both the broad and minor features of our invention are concerned many changes ;in form and detail construction and arrangement may be made without departing from the spirit of our invention, and it isnot our intention to limit ourselves in any instance to the precise details above described.

The gist of one part of our invention resides in causing the type-cleaning end of the brush to be moved into contact with the types through the instrumentality of centrifugal force.

In the practical embodiment of our conceptions we have employed combinations of i devices which are valuable in other associations and which it is our desire to secure hereby. To illustrate: In carrying out the" j idea of a centrifugally-operating cleaner we into the type-field is obtained by connecting have made use of a series of brushes adapted @to collapse in the same manner as an umbrella, and we regard this collapsible-brush gfeature as valuable per 86, whether or not centrifugal force is employed, and in carrying out the idea of a continuously-rotary brush provided with an operating-crank and adapted to move automatically into the typefield we have preferably used centrifugal force to impart to the brushes the desired automatic movement; but we desire to secure this feature broadly, whether the effect is produced by means of centrifugal force or otherwise.
